PACKAGE-TIE.

Specification of Letters Patent. Pat ented Apr, 15, 1919.

Application filed December 29, 1916. I Serial No. 139,607.

To all whom it may concern:

'Be it known that we OTTO KRIsTrAN sevented certain new and usefulImprovements in Package-Ties, of which the following is a specification.

.Thereare already several known forms of apparatus for tying up parcels,bunchesof letters or papers, etc., by means of cord, string, tape, orthe like.

Such apparatus consist of, for instance, a plate of metal or othersuitable material provided with a hole, a pin, or the like, for holdingone end of the cord or string, and with a clamp device for holding theother end of the cord or string.

All these known apparatus, however, generally have several disadvantageswhich make them more or less impracticable. The clamps do not hold thecord or string tightly enough, and it is liable to slip or, at allevents, to be pulled out of its proper position. The apparatus, andespecially the clamp device, have too many projecting parts, whicheasily catch hold of other parcels or other objects adjacent to theparcel to be tied, and thus it frequently happens that the clamp deviceis opened, the string slips out, and the parcel is undone.

It is the object of the present invention to remedy these disadvantagesby giving the clamp device a special shape, so that the string is heldsecurely, and by the absence of all projecting parts which can catchhold of foreign objects thereby causing the parcel to be undone. It isespecially important in this invention that the resilient part of theclamp device is situated below the stationary part, and is therefore notinterfered with when the apparatus happens to touch any foreign objects.

The drawing shows two difierent forms of construction for thisinvention. Figure 1 is a top view of one form of construction. Fig. 2 isa section through the same along the line I.I. in Fig. 1. Fig. 3 showsthe apparatus with the strings wrapped around a parcel, or the like.Fig. 4 is a top view of another construction of this invention.

The apparatus, which may preferably be made of one single piece ofplate, consists ofa plane part 2 and a projecting ear on which should beplaced the thumb of the person using the apparatus, and therefore thispart 4 may be provided with a hole 5 or with corrugations, which willprevent the thumb from slipping on the plate. Furthermore the plane part1 has a notch 6, a projecting lug 7, whichserves as a guide for thesingle string 8 (Fig. 3), when it is to be wrapped around a parcel, abunch of letters, orthe like, and a flap 12 provided with a hole Or apin 13, which serves to hold the string or cord.

l The plate 2 1s prolonged into a tongue 14,

which is bent inward under the plate 2 proper (see Fig. 2) and furnishedwith a boss 15, which projectsup through an opening 16 in the plate 2.Instead of this'opening there may, of course, be a vbulge in the plate 2corresponding to the shape of the boss 15. The tongue 14 pressesresiliently up against the lower side of the plate 2. Between the ear 4and the plate 2 there is a notch 17 and between the flap 12 and theplate a notch 18, which serves to iguide the string or cord, as setforth in the ollowing.

The plate 2 lies on a higher plane than ear 4, the lug 7, and the flap12.

In the form of construction set forth in Fig. 4, there are two bosses 15on the tongue 14 and two corresponding openings 16 in the plate 2.

The apparatus with the string held fast in the hole 13 is used in thefollowing manher for tying up for instance a bunch of letters.

The apparatus is laid on the top of the bunch and held there forinstance by the users thumb, which is' pressed on the part device bypassingit into the notches 17 and 18, as shown in Fig. 3.

This is accomplished by passing the string 8 in between the tongue 14and the plate 2, so that it will rest on the top of the boss or bosses15 and by means of the resilient tongue 14 it is pressed up into theopen-- ing or openings 16 Where it is held securely fast.

If it dsdesiredto undozthe parcel; again, the string is pulled out fromthe intermedi ate space between the plate 2 and the tongue 14, and theapparatus can then be removed and used for a new parcel or bunch of let-7 .ters.

We claim 1. A package tie, comprising a 'slngle piece ofresilient sheetmaterial bent upon itself to Lfor m ad acent integralmembers,
